Answer:
a = 25 m²
b = 5 m
c = 7.94 m
d = 35.73 m²
Code: H I A B
Step-by-step explanation:
<u>Formulae</u>
Pythagoras’ Theorem:
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Area of a square = x² (where x is the side length)
------------------------------------------------------------------------------------------------------
Assuming that all the quadrilaterals are squares.
Side length of blue square with area 16 m² = √16 = 4 m
Side length of yellow square with area 9 m² = √9 = 3 m
Use Pythagoras' Theorem to find the <u>length of b</u>:
Now we have found length b, we can find <u>area a</u>:
Side length of purple square with area 144 m² = √144 = 12 m
Side length of green square with area 81 m² = √81 = 9 m
Use Pythagoras' Theorem to find the <u>length of c</u>:
Now we have found length d, we can find <u>area d</u>:
Code: H I A B
